+## Why
+
+The scaffold provides local Docker Compose development (FN-002) but lacks production deployment configuration. Without Traefik label generation and production stacks, tool instances cannot receive HTTPS subdomains, blocking the core value proposition of the platform.
+
+## What Changes
+
+- **Traefik label generator**: Backend service that generates Docker labels for subdomain routing based on tool instance metadata
+- **Production Docker Compose stack**: `docker-compose.prod.yml` with API, web, Traefik, and PostgreSQL services
+- **Portainer stack definition**: Docker Compose file optimized for Portainer deployment
+- **Dynamic subdomain routing**: Automatic Traefik rule generation for spawned tool containers
+- **HTTPS configuration**: Let's Encrypt or custom certificate support via Traefik
+- **Network isolation**: Separate Docker networks for platform and tool containers
+
+## Capabilities
+
+### New Capabilities
+- `traefik-label-generator`: Generate Traefik Docker labels for tool subdomain routing
+- `production-compose-stack`: Production Docker Compose configuration
+- `portainer-deployment`: Portainer-friendly stack definition and deployment guide
+- `subdomain-routing`: Dynamic HTTPS subdomain allocation for tool instances
+
+### Modified Capabilities
+- None (this extends the existing deployment skeleton)
+
+## Impact
+
+- **apps/api/app/services/**: New Traefik label generation service
+- **apps/api/app/routers/tool_instances.py**: Integrate label generation on spawn
+- **deploy/**: New production deployment files
+- **docker-compose.prod.yml**: Production stack definition
+- **docs/deployment.md**: Updated deployment instructions
